Recovering the BIOS password from a Panasonic CF-U1 mk2 (AMI Aptio UEFI)

A mess of my own making

While messing with a CF-U1 handheld PC that I bought off ebay I managed to mess up the BIOS and it seems it reverted to previous settings which included an unknown BIOS password, it would however still boot into windows. Since I could still boot windows I was able to dump the bios flash using AFUWINGUI.EXE the version I used was 3.09.03.1462 which is available here:

Flashing an unbranded smart lightbulb to Tasmota

Whilst on holiday last week I thought i would do something productive but that seemed like work so I bought some cheap noname wi-fi smart LED lighbulbs off ebay and flashed them with Tasmota firmware, since the particular bulb I bought wasnt listed on the Tasmota Device Templates Repository and I have no idea if they accept an entry for a bulb with no identifying marks I thought i'd put something here incase its of use to anyone.

Reliability: I have at this point had 10 of these bulbs running for about a week, one of them has just died.

TL;DR

The pinout and device string for this light:

• GPIO4 Cold White PWM 4

Flashing an ENER-J SHA5264 wifi smart plug to Tasmota

After having messed with an unbranded wifi lightbulb I thought I would have a look at a smart socket with energy monitoring. This particular model didn't have an entry on the Tasmota device templates repository nor was it listed as not compatible so I thought I would take a chance on it being ESP8266 based, the screws in the case also suggested it could be opened without damage incase it required serial flashing or a multimeter to work out how the energy monitoring chip was connected which is very helpful and saves destroying a plug for science.

TL;DR

The plug is Tuya based and can be flashed with Tuya-Convert for now, the pinout and device template for this power monitoring plug:

• GPIO0 Button 1
• GPIO4 BL0937 CF

Flashing an ENER-J SHA5207 smart power strip to Tasmota

After having messed with an unbranded wifi lightbulb and a ENER-J power monitoring smart socket I thought I would have a look at a smart power strip with USB also from the company ENER-J. This particular model didn't have an entry on the Tasmota device templates repository nor was it listed as not compatible so I thought I would take a chance on it being ESP8266 based, since the ENER-J smart socket was there seemed a good chance the power strip would be too.

TL;DR

The power strip is Tuya based and can be flashed with Tuya-Convert for now. Absent any numbering on the power strip I chose to number the sockets starting from where the power enters the strip with the USB sockets last, so socket1 is the one closest to the power cable. The pinout and device template for this
